45 Claims.

My invention relates to copyholders and the objects of the invention,generally stated, are as follows: 7 To provide' a highly effective andeasily manipulated copyholder for indicating the lines successively,line at-a-time as they are being copied.

To provide simple and efficient means for intermittently, successivelyand noiselessly feeding position to which the work sheet carrier mayhave been intermittently fed.

To provide improved means whereby the copyholding member may be readilyexpanded to its fullest height during the feed of the copy, or may bereadily collapsed to the first line indicating position.

To provide a construction of the character 'hereinbefore set forth withmeans whereby the copyholder may be further collapsed from its firstwriting line position to a position of nonuse where it may be moved intoa drop cabinet of a typewriting machine with said machine, and withoutinterfering with the movement of the machine into and out of thecabinet.

To the above and other ends which will hereinafter appear, my inventionconsists in the features of construction, arrangements of parts andcombinations of devices set forth in the following description andparticularly pointed out in the appended claims.

- Figs. 11 and 1 2 are detail perspective views of the detents for partsof the structure to be hereinafter described.

Generally stated, the present construction involves a work sheetcarrying member that may be intermittently and noiselessly fed to anexpanded position, represented in dotted lines in. Fig. 2, and may atwill-be readily and noiselessly returned to the first line indicatingposition, represented in Figs l and 3. When it is desired to fullycollapse the copyholder to the full line position shown in Fig. 2, andas represented in Fig. 5, to house the copyholder with the typewritingmachine in a drop cabinet, this may be readily and noiselessly effected,as will hereinafter appear.

In the accompanying drawings I have shown an L-shaped base comprisingtwo wooden members I and 2 which are preferably detachably united orhinged together by suitable means to enable the copyholder to becompactly packed when desired. In the present instance screws 3 firmlyconnect the members I and 2 together. The base member .I constitutes asupport for the copyholder proper and the member 2 constitutes a supportfor the manually controlled handle and certainof the connectionscontrolled thereby. However, the so-called base members I and 2 may bedispensed with and the copyholder secured directly to the top of a deskor table on which itis to be supported. For the purpose of the presentcase the base members I and 2 may or to the top of the disk or table.

be regarded as the equivalent of a desk or table to which the copyholdermay be secured.

As best shown in Figs. 3 and 5 a fixed guide tube or sleeve 5 is fittedat its lower end in an opening in a metal plate or block 6 secured byscrews 6 to a metal base plate 6 which in turn is fastened by screws Ito the wooden base member I, Received and telescoping in the guide tube5 is a tubular member 8 received at the upper and lower end portionsthereof with a snug fit in the guide tube 5 which nevertheless permitsthe member 8 to slide freely In a like manner within the guide member 5.an inner telescoping solid rod 9 is received in the tubular member 8 andhas a snug fit at the top and bottom thereof within said member 8. Anysuitable means may be provided for limiting the upward telescopingmovements of the members 8 and 9 relatively to one another and to thesupporting tubular member 5. ring more particularly to Fig. 5, it willbe seen that the member 8 is provided at the lower end thereof with ahead I0 that has a circumferential flange that extends beyond the outerdiameter of the tube 8 and is adapted to coact with a shoulder I I nearthe upper end of the guide tube 5 to limit the upward movement of themember 8. In a like manner the rod 9 is provided with a head I2 that hasa circumferential flange that projects beyond the diameter of the member9 and is adapted to coact with a shoulder I3 near the upper end of thetubular member 8 and thus v limit upward movement of the member 9relatively to the tube guide member 8.

In order to further secure the tubular guide member 5 in place I providea cross brace I4 (see Fig. 3). which is secured at its ends by screws i5to upright supporting members I6 The members I6 constitute rearwardlyand inwardly turned parts of an upright sheet metal supporting plate I6that is coextensive with the width of the copyholder and is fixedlysecured at the lower end thereof to the metal base plate 6. The upperedge of the plate I6 terminates at about the height of the bar I4, asshown in Fig. 5. The cross brace I4 is fixedly though detachablyconnected to the fixed sleeve 5 by a screw II, as shown in Figs. 3 and5, to firmly hold the sleeve in place.

I preferably provide a rubber disk I8 in the lower end of the tubularguide 5 and which rests upon a closing block I9 in the lower end ofsaidtubular guide. The purpose of this construction is to seal the lowerend of the tubular guide so that said guide and the member 8 may operatein the nature of a dash-pot to prevent too rapid a movement of the guidemembers and the parts connected therewith when they return to collapsedposition. In a like manner the inner guide member 9 in a measure coactswith the tubular member 8 to form a dash-pot.

Referring more particularly to Fig. 3 it will be seen that the upper endof the inner rod 9 is connected by a screw 20 to a cross head 2|. Thiscross head carries two depending pins 22 near the outer ends thereof,each provided at its lower end with a head 23. These pins 221 arereceived and play freely in openings in a bracket plate 26 that issecured to a member of a lazy :tongs, designated as a whole by thereference numeral 25. This connection between'the headed pins '22 andthe lazy tongs provides a lost motion connection between them, so as. toafford a limited extent of independent movement between such parts whenthe copyholding member Thus, by refer- 30 is closely approaching and isbeing moved from its fully collapsed position in a manner and by meanswhich will be hereinafter described. As the lazy tongs are moving totheir fully contracted position from that shown in Fig. 3 the rod 9 willbe arrested first. The bracket 24 will then move down independently ofthe arrested pins 22 during the final collapsing movement of the lazytongs; the heads 23 limiting the final extent of this independentmovement. During the upward movement of the copy-sheet carrying member39, by means to be hereinafter explained, the lazy tongs will beexpanded, first carrying the bracket 24 up on the pins 22 until saidbracket reaches the cross head 2|, as shown in Fig. 3. This will resultin lifting the rod 9 and successively expanding the telescoping members9'and 8 relatively to the fixed member 5. Each of the two lower membersof the lazy tongs is connected by a pin and slot connection 26, 21 tothe upright supporting plate I6, so as to permit a slight horizontalmovement of these lowermost members of the lazy tongs during theexpansion and contraction of the lazy tongs.

Ina like manner the uppermost members of the lazy tongs are connected bypin and slot connections 28, 29 to a sheet metal member 30 that extendsthroughout the width of the copyholder and is bent to the rear at theupper end thereof as shown in Figs. 1, 5 and 6. This member 39constitutes a copyholding member as will hereinafter more clearlyappear.

The lazy tongs are further guided by a pin 25 carried thereby and whichmoves in an upright slot 25 in the supporting plate I6 as best shown inFigs. 3 and 4.

From the foregoing description it will be understood that as the lazytongs are expanded by an elevation of the copy-carrying member 39 therod 9 will be elevated. On the other hand; when the lazy tongs arecontracted during the lowering of the copyholding member 39 the rodirrespective of the position to which the copy holding member 39 israised or lowered. The lazy tongs also maintains the copyholding memberagainst a pivotal movement around the telescoping guide members.

In order to further properly guide the copyholding member 39 and preventit from moving forward or back or sidewise, I have provided a dependingsheet metal guide 3| which is fixedly secured at its upper end, asindicated at 32, to the copyholding member 39. The guide member 3| isslotted vertically at 33 to receive a headed pin 34 carried by one ofthe members of the lazy tongs. This guide in cooperating with the lazytongs also prevents a side displacement of the copyholding memberrelatively to the lazy tongs.

From an inspection of Figs. 1, 2 and 3 it will be seen that thecopyholding member 30 is provided at the ends thereof with rearwardlyextending bracket arms 35. Each bracket arm is pierced to receive one ofthe longitudinally extending bearing end portions 36 of a bail 31. Eachpart 36 is surrounded by a coiled spring 38 which is fixed at one endthereof to a collar 39 secured by a set screw 49 to the companionbearing arm 36. The other end of the spring is fixedly secured to thecompanion bracket 35, as indicated in Fig. 12. As shown in this figurethe end of the spring 38 which is connected to the associated bracket isreceived through a pierced opening therein and extends upward outside ofthe bracket where it is provided with a raised portion 4! that coactswith a crank arm portion 3-2 of t -e bail and constitutes a detent tohold the bail in its released position. Each spring 38 is shaped to formsuch a detent so as to maintain the bail in a substantially horizontallydisposed released position when the bail is shifted to such position.The cross bar of the bail extends across the copyholder and is providedwith a series of rollers 43 which by means of the springs 38 are pressedagainst the depending portion of the copy carrier 30, or the interposedflexible copy sheet supporting member 44, as will hereinafter moreclearly appear.

A second sheet metal clamping member conforming in part to the shape ofthe work sheet carrying member 30 is secured thereto by screws The lowerclamping edge 4'! of this plate bears against the upper edge of theflexible sheet or member 44 and with the aid of the screws 46 fixedlyconnects the upper end of such flexible member and the copyholdingmember 35. The

bail 31 is effective to clamp the upper end of a sheet to be copiedagainst the depending portion of the copyholder 30 or the sheet 56interposed between said copyholding member and the bail, and therebycause the copy sheet to be elevated with the copyholding member 30 asthe latter is intermittently fed upward, as will hereinafter moreclearly appear.

The lower end of the flexible sheet 44,'which may be of a textile fabricor other suitable material, is secured to a roller 48 mounted at itsends in bearing brackets 69 carried by the metal base plate 6. Thisroller is provided with a coiled spring 50 (see Fig. 5) which tends toturn the roller in a clock-wise direction as the parts appear in thisView and to take up and wind on the roller the flexible sheet 44 as thework sheet carrying member 30 moves down from an ele- 0 44 primarily tomaintain it taut at all times, al-

vated position. The purpose of the flexible sheet 44 is to provide asupport against which the copy sheet or sheets may bear to prevent thelatter from coming in contact with the lazy tongs or other working partsof the structure when the member 30 is in an elevated position. Theforce of the spring is exerted on the flexible sheet though some of theforce of the spring is exerted to return the copyholding member 3|] andthe parts connected therewith when said holding member 35 is lowered.This latter effect, however, is unnecessary, since the weight of theparts, ordinarily is sufficient to return them to lowered position.

From a consideration of Figs. 1, 2 and 3 it will be seen that each ofthe upright portions 16 has a bracket 5! secured thereto, at 52, nearthe upper end thereof. Each bracket is provided with a cylindricalrubber buffer 53 with which the associated bracket 35 coacts to limitthe downward movement of the copy-carrying member 35 when the lattermoves down to its lowermost position, shown in full lines in Fig. 2.These rubber buffers therefore constitute the means for limiting thedownward movement of the copyholding member 30 and the parts carriedthereby. This is a fully contracted position of the copyholder to enableit to be conditioned for non-use or to enable it to be received in adrop cabinet with the typewriting machine when the latter is received insuch cabinet.

I have provided a line indicating plate 54 which inthe present instanceis mounted on lazy tongs comprising two members 55 and 56 (see Fig. 1)pivotally united at the centers thereof, as indicated at 51. One end ofthe member 55 is pivotally connected at 58 to the line indicating plate54 near one end thereof. The other end of this member 55 is pivoted at59 to a block 60 mounted for sliding and pivotal movement on the headedpin 6|. Said pin projects from an arm 62 fixedly connected to a rockshaft 63 that receives a bearing in the brackets 5| and extends in therear of the eopyholder from side-to-side thereof. A coiled expansionspring 64 surrounds the shaft 53 at one end thereof and tends to exertits force longitudinally on the shaft to move it to the right, or to theleft as the parts appear in Fig. 3. Secured to the shaft 63 near theother end thereof is a crank arm 65 provided with two stops 65 whichcoact with a fixed pin 5? projecting laterally from the outer face ofthe companion bracket 52. The arm 55 is provided with two openings orrecesses 68, one or the other of which is adapted to coact with arounded projection 69, as shown in Fig. 11. This constitutes a detent tohold the shaft 63 and the parts carried thereby against accidentaldisplacement from either the full line or the dotted line position shownin Fig. 2. In the full line position the parts are positioned fornon-use or for storage and with the line indicator overlying the worksheet carrying member 35, whereas in the dotted line position the partsare conditioned for use. The left-hand end of the lazy tong member 55 ispivoted at 18 to a block H which in turn is mounted to receive a pivotalmovement around a headed pin or screw 12 connected to the lefthand arm13 which corresponds to the arm 62 that is fixed to the shaft 63.

From the foregoing description it will be understood that the lineindicating plate 55 not alone is adapted to move with the shaft 63 fromthe dotted to the full line position shown in Fig. 2, but that saidindicating plate is also free to turn on its pivotal center 6!, 12, theparts being sufiiciently friction tight to hold the line indicator inany such angular position to which it may be turned on its pivotalcenter. This enables the line indicator to be adjusted closer to orfurther from the copy to compensate for various thicknesses of copy, andalso to be adjusted out of the path of the ball 3? and the rollers itcarried thereby, and enables the latter to clear the-line indicator whenthe copy-holding member is lowered to its lowermost position.

It also will be understood that the lazy tong mounting provided for theline indicating plate 54 enables it to be moved on its supports 60, ll

. to various positions parallel with its pivotal center 6!, 12, therebyenabling the line indicator to be moved to and maintained at differenteleva-- tions. It will be understood that in such movements of the lineindicator the right-hand end of the lazy tong section or element 56 willreceive a sliding movement relatively to the line indicating plate byreason of the pin and slot connection l4, 15 by which said lazy tongelement is connected with the line indicating plate 54.

In order to limit the downward movement of the copy-carrying member 30and the parts carried thereby to the first line indicating position, Ihave provided automatically operating devices which I will now describe.Referring more particularly to Figs. 1 and 3 of the drawings it will beseen that two stops 76 are pivoted on the headed pins 28 which connectthe lazy tongs to the copy-carrying member 30. The weight of these parts16 tends to move them to the posij tion indicated in Fig. 3 where theyare adapted to coact with the rubber buffers 53 and limit the descent ofthe copy-carrying member 30 and the parts carried thereby. When it isdesired to fully collapse the copyholder to the position indicated infull lines in Fig. 2 and in Fig. 5, it is merely necessary to swing themember 16 inward towards the center of the copyholder so that the lowerends of said members are out of cooperative relation with the rubberbuffers 53. The copyholding member 3!) may then drop by gravity, aided,if this be found necessary, by the pull of the spring 50 exerted throughthe sheet 34, to lowermost position. This movement is free from controlof the members 16 which at this time coact with the inner sides of thebuffers 53 which hold them in ineffective position. As soon, however, asthe copyholding member 30 is again elevated to a position where thearresting members 16 are free from contact with the buffers 53, saidarresting members will by gravity move to the effective position shownin Fig. 3, where the lower ends of said members are adapted to coactwith the bufiers and arrest the member 30 in its next downward or returnmovement. The effect of this arrest of the copyholding member by thearresting devices 16 is to locate the copyholding member and the partscarried thereby in the first writing line position where the lineindicator 54, if properly adjusted, will register with the first line ofthe matter to be copied.

The means by-which the copyholding member 30 is intermittently elevateda line space at a time will now be described.

A bracket '17 (see Figs. 3 and 6) is secured to the rear side of thedepending portion of the copyholding member 3!], as indicated at 18. Ametal rod 19 is secured at its upper end to said bracket and extendsthrough openings-in guide brackets 80 and 8! secured by screws 82 tomembers of the lazy tongs 25. The lower end of the rod 19 is threaded at83 for cooperation with a threaded bushing 84. This bushing is receivedand threaded into the upper end of a flexible controlling or drivingmember or follower 85 which is in the nature of a closely coiled springthat extends down from and forms a continuation of the rod 19, asindicated in Fig. 3. This flexible member or driving device 85 extendsin a substantially straight line to and tangentially of a drum 86 onwhich the flexible member is adapted to be wound. That portion of theflexible member which extends in a substantially straight line to thedrum intercepts the plane thereof as represented in Fig. 6 and isreceived in a channel or recess 81 in the front side of the drum, oneend of said flexible connection being secured to the drum, as indicatedat 88, in Fig. 3. I prefer to insert a flexible sheet metal strip 89within the coiled flexible controlling member 85 throughout the lengththereof in order to provide against a lateral deflection of that portionof the flexible member which is unwound from the drum and render itstiiTer against lateral deflection. From an inspection of Fig. 6 it willbe seen that the drum 86 is slightly inclined so as to facilitate astraight line movement of the flexible member in its movement onto andoff the drum. I also provide guide members 90, 9|, 92 which form partsof a bracket 93 fixedly secured to the metal base 5, as best shown inFigs. 4 and 7, in order to direct the flexible member 85 in its movementto and from the drum and to the channel 87 therein, the guide members90, SI and 92 also preventing a lateral displacement of the flexiblemember from the channel in the drum. The flexible member 85 acts with athrust or pushing force against the copyholding member 30 to elevate it.

Manually controlled intermittently actuated means are provided to turnthe drum in an anti-clockwise direction, as the parts appear in Fig. 7,and thereby efiect a longitudinal thrust of the flexible member toelevate the copycarrying member 35. Said means include a ratchet wheel 9secured by screws 95 to the drum to turn therewith. From an inspectionof Fig. 4 it will be seen that the drum turns on a headed pivot screw 55received at its threaded end 97 into a tapped opening in the bracket 93.A flanged bearing member 98 is fixedly connected to the drum at 99, andit is this member 98 that receives a support on the pivot screw 96.

An actuating arm Hill receives a bearing on the sleeve-like portion dillwhich constitutes a part of the member 98. This depending actuating armconstitutes a pawl carrier having a feed pawl H12 pivoted thereto at W3.A flexible sheet metal arm iM projects from the pawl and its flexiblefingers Hi5 bear against the inner side wall of the drum 86. Theengaging nose of this pawl m2 is adapted to coact with the teeth of theratchet wheel 94, as shown in Fig. 7. An actuating link 305 is pivotedat H]? to the pawl-carrying arm i553 and a movement of said link fromnormal position in the direction of the arrow in Fig. 7 is efiective toturn the ratchet wheel 94! and the drum 88 secured thereto in ananti-clockwise direction. As the link moves in the direction of thearrow in Fig. 7 the frictional engagement between the fingers Hi5 andthe inner face of the drum causes the pawl I92 to turn on its pivot IE3at the first portion of the movement of said link and to thus engage theratchet wheel. When the link IE6 is moved in the opposite direction asindicated in Fig. 8, the frictional engagement of the fingers i 635 withthe inner face of the drum tends to cause the pawl N12 to turn on itspivot I63 out of engagement with the teeth of the ratchet wheel 94, sothat in the return movement of the pawl with its carrier Ifiil the pawlwill be maintained out of engagement with the ratchet wheel and thusprovide a noiseless ratchet. In order to limit the movement of the pawlout of engagement with the ratchet wheel, I have provided a fixed stoppin m8 on the pawl carrier I98 and which coacts with the pawl to limitits outward movement.

In order to provide means for holding the drum against reverse rotationin a clockwise direction, I have provided a holding pawl I09 pivoted atM5 on the bracket 93. A contractile spring ii I is anchored at one endon a pin H2 that projects from the bracket 93. The other end of thisspring is connected to the holding pawl Hi9 below the pivotal centerthereof. The force of this spring is therefore exerted to move the noseof the pawl 509 into engagement with the ratchet wheel 94. A dependingend H3 on the pawl extends into the path of movement of a laterallyprojecting pin i i i on the link I06. As the link H36 moves inthedirection of the arrow in Fig. 8 the pin H4 engages the depending endII 3 of the holding pawl and turns it on its pivot IIO to its releasingposition, as shown in Fig. 8. In order to limit the extent of releasingmovement of the pawl I09 I provide a stop lug II5 that forms part of thebracket 93 and extends into the path of said pawl. The pawl I09, likethe pawl I02, is likewise provided with a flexible arm II6 havingflexible teeth II! that bear against the inner side wall of the drum 85.The effect of this frictional engagement between the arm H6 and the drumis to automatically disengage and maintain the holding pawl disengagedfrom the teeth of the ratchet wheel 94 when the drum is moved in ananticlockwise direction by the feed pawl I02. As soon, however, as astep-by-step feed movement of the drum is completed and it starts toturn in the opposite direction, then the frictional engagement willcause the pawl I09 to engage the ratchet wheel and prevent a reverserotation thereof.

The parts are maintained as they appear in Fig. 7 during the linespacing feeding operation of the drum in an anti-clockwise direction. Ihave, however, provided means for freeing the drum from control of itsintermittently operating feeding means when it is desired to lower thecopyholding member 30. This is effected by a movement of the link I06 tothe left from its 30 normal position as shown in Fig. 8, instead of to40. frictional engagement of the arm I04 with the inner face of thedrum. The drum being freed at this time from the control of the pawlsI02, I09, is free to turn in a clockwise direction as shown in Fig. 8,thus enabling the copy sheet 45. carrying member 30 and the partscarried thereby to move down to the first line indicating position shownin Figs. 1 and 3 where it is arrested by the stopping devices I6coacting with the; rubber buffers I3. Should it be desired to stillfurther lower the copy-carrying member 30, this may be done ashereinbefore indicated by moving the stop members 16 inward to disengagethem from the buffers 53 when the copy-carrying member 30 is free tomove to its lowermost position, shown in Fig. 5 after the pawls I09 andI02 are released as explained.

The means by which motion may be transmitted to the link I06, either toeffect an intermittent feed of the drum or to free the drum from thecontrol of the actuating devices therefor, will now be described.

As best shown in Figs. 1, 2, 9 and 10 the righthand end of the link I06is pivoted to a crank arm II8 which is fixedly secured to a shaftsection II9 supported in a U-shaped bearing member or bracket I securedto the right-hand upright portion I B as indicated at I2I. The forwardend of this shaft section forms a tubular bearing I22 that is slottedlongitudinally on- 70' opposite sides, as indicated at I23. A shaftsection I24 carries an enlarged end I25 that is received in the tubularbearing portion of the shaft section II9. oppositely directed pins I26carried by the enlarged portion I25 are received in the slots I23 toafford a limited sliding motion of the shaft section I24 relatively tothe shaft section II9, but to connect the two shaft sections,nevertheless, to tiun together, for purposes which will hereinafter moreclearly appear. The shaft section I24 is provided with an enlargedtubular portion I21 tapped to receive pointed set screws I28. A thirdshaft section I29 is received at one end in the tubular enlargement I 21and is fixedly connected thereto by the screws I 28 both to turn and tomove longitudinally therewith. The po;nted ends of the screws I28 arereceived in an open ended groove I29 in the shaft section I29. By thesemeans the shaft I24, I29 may be relatively adjusted to lengthen orshorten the compound shaft to accord with difierent lengths oftypewriting machines with which the copyholder may be associated. Theforward end of the shaft section I29 is received in and projects througha bearing opening in a bracket I30 secured by screws I3I- to the basemember 2. A finger piece I32 is provided at the outer end of a crank armI33 secured to the outer'end of the shaft section I29 where it extendsbeyond the supporting bracket I30. The member I33 is also provided withan arm I34 that carries a screw stop I35 held in its adjusted positionon said arm by a lock nut I36. The free lower end of the screw stop I35coacts with a stop face I31 on the bracket I30 to limit the movementtransmitted to the shaft I29, I24, I I9, in one direction, that is inthe direction of its feed movement. It will be understood, therefore,that an adjustment of the screw stop I35 is effective to regulate theextent of line spacing movement transmitted to the compound shaft justdescribed and the feed drum 86 controlled thereby. adjustment andregulation of the device to set it to accord with the spacing on thecopy used on the copyholder.

I Referring more particularly to Fig. 10 it will be seen that the armI33 is provided with a beveled face I38 adapted to coact with a beveledface stop I39 carried by and projecting laterally from thebracket I30 tolimit the return movement of the arm I33 and the parts controlledthereby to normal position. It should be explained at this point thatthe compound shaft I29, I24 is free to receive a longitudinal move mentin its bearing I 30, as well as a turning movement in said bearing. Acoiled expansion spring I40 surrounds the forward section I29 of thiscompound shaft and is fixedly connected at one end to a collar I4Isecured to the shaft section I29 by a set screw I42. The other end ofthis spring is fixedly connected to the bracket I 30. The springtherefore has a twofold function, that of turning the shaft to normalposition with the stops I38, I39 in contact and also of exerting a forcelongitudinally of the shaft to maintain the hub of the arm I33 incontact with one side of the bracket I30. The effect of this is tomaintain the shaft sections in the relation shown in Fig. 9 with thepins I26 seated in the slots I23 near the rear ends thereof. Should theoperator desire to release the drum from control of the intermittentlyoperated actuating means which cooperate therewith, it is merelynecessary to effect a downward movement of the finger piece I32 from theposition shown in Fig. 1 where the arm I33 is arrested by a stop I33 Theeffect of this movement is to cause the compound shaft I29, I21 to bemoved forward against the expansion force of the spring I40 due to theaction of the cam faces I38, I39 which tend to bring about thislongitudinal displacement of the This affords an,

compound shaft when force isexerted on the finger piece in the directionreferred to. This turning movement of the shaft from normal position ina direction opposite to that which it takes during the intermittent feedoperation is effective to move the link I06 in the direction of thearrow in Fig. 8 and effect a release of the pawls i 92, 1 E39 fromengagement with the ratchet wheel 96 as shown in said figure, thusfreeing the drum from control of its feed mechanism. The weight of thecopy-carrying member 30 and the parts connected therewith together withthe force of the spring 50 is then'efiective to cause the member 38 tobe lowered, to turn the drum 8B and to wind the flexible drivingconnection 85' on the drum.

Referring more particularly to-Figs. 1, 2 and 4, it will be seen that Ihave provided a rear sheet metal cover plate 5 13 at the rear of thecopyholder, said plate being detachably secured in place by screws Mdwhich engage in threaded openings in rearwardly projecting posts I45 onthe portions Ili of the supporting plate IS. The sides of the coverplate M3 are bent forward (see Fig. 4) to meet the members H5 and theworking parts are thus fully housed when they are in the contractedposition.

The copyholder is comparatively simple in construction, is easilymanipulated, is highly effective in use, may be quickly conditioned forstor ing and is substantially noiseless in its operation.
